1. A method for controlling temperature in a conditioned enclosure comprising:

  • controlling temperature within the conditioned enclosure according to a setpoint temperature, an initial value of the setpoint temperature being from a preexisting schedule and representing a temperature suitable for when one or more persons are occupying the conditioned enclosure;

    periodically determining occupancy based on data received from one or more occupancy sensors adapted to detect occupancy within the conditioned enclosure;

    periodically updating the setpoint temperature upon expiration of a predetermined time interval during which no occupancy has been detected, the updated setpoint temperature requiring substantially less energy to maintain than the initial value of the setpoint temperature; and

    periodically modifying the predetermined time interval based at least in part on received manual settings that indicate occupancy following the updating the setpoint temperature.
